Leak/Discharge??? Help

Morning,
After buying my 2004 Tacoma from my father-in-law I detailed the engine compartment and in doing so noticed a considerable build up around the battery/inner fender/pwr steering pump and A/C pump. I could not find active leak...so shrugged shoulders and finished cleaning. Now just 2 months later I look and there is a slight build up again in the same area?? Feels sticky, not like oil or powersteering fluid (no drops on driveway). Could this be a leaky A/C pump or line (air blow fairly cold)? Is freon sticky??

 

hahahaha Originally by the title I was thinking this was something you should go to the doctor for.

What color is the build up?

 

Need to get under their, but appears black or "dark".

 

maybe snap a pic if you get under there.

 

will do. I could have dealer inspect, but at $85 per hr...dammmm!

 

Yea man screw the dealer some pics will help everyone here determine or at least maybe narrow down the problem
